Question

Intake of small quantity of methanol can be lethal. Comment.

✓

Answer

Methanol $\left( CH _3 OH \right)$ is oxidised to methanal (HCHO) in the liver.
$2 CH _3 OH + O _2 \rightarrow 2 HCHO +2 H _2 O$
Methanal (HCHO) reacts rapidly with the components of body cells. It causes the protoplasm of the cells to coagulate. It also affects the optic nerve and causes blindness. Therefore, intake of small quantity of methanol can be lethal.
